Title: Support substrate for forming piezoelectric film, piezoelectric element, and ink-jet recording head
Inventor: KUBOTA JUN
IPC: H01L41/39
Filed: 2003-01-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a support substrate for forming piezoelectric films that improves thermal stability and stability with time in a piezoelectric element, the piezoelectric element manufactured by using the support substrate for forming piezoelectric films, and an ink-jet type recording head.  <P>SOLUTION: The support substrate for forming piezoelectric films has a constitution provided with at least a substrate and a lower electrode layer. The substrate is characterised in that the lower electrode layer consists of a platinum layer having an in-plane stress of -200 MPa or more and 500 MPa or less, and the platinum layer is arranged in the outermost layer of the support substrate for forming piezoelectric films.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Grounding structure of connector of circuit board
Inventor: TOKUNAGA TAKASHI
IPC: H01R31/06
Filed: 2003-02-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide grounding structure of a connector installed on a circuit board, wherein the circuit board (a mid plane) is thin, and shielding effect is further improved.  <P>SOLUTION: A half 1a of the connector and the other half are installed on a front and rear surfaces of the circuit board, respectively. Both halves has a housing 1a1, and a plurality of first ground plates 1a2 held by the housing; and a plurality of second ground plates 1a3 held by the housing and crossing respective ground plates in a grid, respectively. A plurality of terminals 1a2b and 1a3b formed in the respective ground plates are press-fitted zigzag with a plurality of through-holes formed in the board, respectively. A plurality of contacts for signal arranged across both halves are inserted to the through-holes, respectively. Additionally, at least a part of the contacts are surrounded by the respective ground plates.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
